Congratulations to the whole Clojure community: 4Clojure just passed 50,000 solved problems and 1,800 user accounts! These are big numbers for a kata site which has spread only via word of mouth. All of the devs are really looking forward to 4Clojure getting even bigger - scalability issues are a great problem to have!
Again, a big thanks goes out to all of our users. If you want to make 4Clojure even better, we’re always looking for help! Submit a problem (you need to solve 50 problems first), follow or patch the site via github, or simply come hang out with us on #4clojure.
